PLUMBING FITTING.

Application filed November 11, 1924. Serial No; 749,207

This invention relates to plumbing fittings and more particularly tosockets for pipes and for fittings employed in pipe lines.

It is an object of the. invention that of providing an improved socketor hub for pipes and )lPG fittings, which will permit an easy closing orcompletion of the pipe line, or 'pern'iit an easy dismemberment of thepipe line, without injuring the same, or permitting an additiontheretoof a branch line or lines without any dilficulty.

It is another object of the invention that oi providing an improved, butsimple and efficient socket or hub for plumbing fitting or pipe sectionswhich is cheap to manufacture, and which is admirably useful in theplumbing trade; which is simple in construction, but very sturdy andappropriate for the purpose intended; and which can be em ployed in thegeneralplnmbing trade without in the least changing the standardequipment now in use.

A further object of the invention is that of providing anew and improvedsocket for pipe line sections, or fittings, which is split in sectionsand which easily permits the application of such section or fitting tothe pipe line.

Further objects and advantages, together with the distinguishingfeatures of the invention will appear as the specification proceeds ofwhich the accompanying drawings form a part; which drawings, it isunderstood, illustrate but one example or embodimen t of the invention,to which I do not limit myself, for the same can be easily changed orvaried, without in the least departing itronithe spirit of my invention.

Referring to the said illustrated embodiment Figure 1 shows oneembodiment of the invention as applied to a pipe line, and moreparticularly to a Y fitting;

a fitting, such as a pipe turned at an angle.

Plumbers find, with the present standiird plumbing equipment forbuilding drainage work, considerable diliiculty in closing up or puttingin the last pipe section of the drainage pipe, because the end of onesection must be inserted in the socket of the next adjacent section. Inclosing pipe lines t..c plumber or plumbers 'make as many as il orjoints in the neighborhood where the line is closed, so that the end ofone portion oi the line may be inserted in the socket oi? the lastsection in the line by swinging the line and curving the same back andforth until that end enters in its socket. For such swinging and curvingit is necessary that the line has as many joints as possible so torender it more or less flexible under side pressure.

Whenever a pipe line needs to be cleaned plumbers have to resort tocutting the line so as to take out of it one of the sections. before theothers can be removed. Likewise similar operation must be gone throughwhenever it is necessary to add to an existing line an auxiliary or abranch line.

Such difiiculties and shortcomings are constantly pres n; in the presentsystem, but through the aid of the present invention they are avoided aswill hereinafter appear.

Referring to the drawings at A, l have shown a plumbing fitting fordrainage pipes commonly known as a Y fitting. This Y fitting comprisesthe main body 10, the branch pipe 11, the socket or hub 12 on the end ofthe branch. pipe 11, the end 13 forming a part of the main body andadapted to be fitted into the socket or hub 14 of the adjoining pipesection 15. At the upper end oi the fitting is located the socket or hubin which fits the lower end of the other adjoining pipe section 21; Thissocket 20 in all respects serves the same purpose as sockets 12 and 12i, but it is constructed different than these latter sockets 13 and 14as illustrated in the drawings,

As it will be noted from Figures 1 and S and -lthe socket 20 is split intwo sections, to wit, section 25 and section 26. The section 25 isintegral with the main body 10, whilethe section 26 is removable.

The splitting of the socket is preferably eltected on a vertical planefor the length of the socket, and on an inclined plane below the socketforming meeting faces and en the sectien 2 an meeting faces liq 33 and34; on section The meeting face 31 being extended to the reinforcingmemher 32 which is integral with the body of the pipe.

The sections are formed with integral flanges 35 and 36 respectively.These flanges confirm at their inner faces with each other, and betweenthem arranged for the purpose of preventing leaking a gasket 40, whichgasket may be made of the material suitable for the purpose such as'bre, rubber, or metallic alloy.

The section is formed with a groove stl which extends substantially thefull length of the flange The section 26 is provided with a bead 4-2extending the full length of the flange 36, which bead may accommodateitself into the groove ll. From the heretofore description it is seenthat by means of the groove l1 and head 42 the section 26 can easily bealined with the section 25 and act as guiding means for quickly locatingthe two sections together. The two sections are held together with thegasket 40 between them, by means of bolts %8 passing through the flangesand 36, the number of which bolts may be varied as the cases mayrequire. In the present illustra ti'on there appearing live belts, butit is clear that any number may be employed. The bolts may screwdirectly in threaded holes in the flanges or may be provided with nuts.In the illustrated example the screws are thre'adedin the holes in theflange 35. The gasket is pressed'at at) so as to form a groove at oneside and a bead on the other to contorln to the head 42 and to thegroove ll. r a

The section 26 is preferably formed with a comparatively straight memberwhich, as is seen from the illustrations, it is alin ed withthereinforcing member on the body 10. Both the reinforcing member 32 andthe member 50 are formed with alined holes, one of which, the one in thereinforcing enlargement 32, being threaded to receive the threaded lowerend of the one of thebolts -18.

So it is seen from the, heretofore description that by providing one orthe sections of pipe line, or a fitting thereof. with a split socket orhub, substantially like the one illustrated and described. the line canbe easily closed by inserting therein as the last member or componentpart that section or fitting provided with the split socket. This isaccoinplish'ed by inserting in the re m'ai-ning open socket in the line(before the last section is inserted) the end of the section or fittingI ro'vidd with the split socket, (such as and b drawing toward the endotth othr secti F yet a" l'h'sed iii trains sea as 23.) so as to partlyenvelop that end in the secti0n 25. Then the section 26 is locked in itsplace against the section 25, after the gasket 40 has been arranged onthe flange 35, and the bolts 48 inserted in the holes in the flanges 35and 36 her1netical'ly tightened. Then the space left between the innertace ot the split socket and the outer face of the section endsurrounded by the said split socket is packed with a filling oaknm andlead, as is presently done in plumbing. Such packing of oakum and lead Ihave designated by the numeral 51.

As it has been mentioned herein the split socket 20 can be formed on anyof the lit tings generally employed in plumbing. In Figure 5 the splitsocket 20 has been shown as replacing one of the sockets ot a crossfitting" it being plain that any other of the remaining sockets canlikewise be replaced by a split socket. In Figure 6 I have shown thesocket or a bent section as being replaced by a split socket 20. In bothof these figures I have also shown the ends of the sections adjoiningthe split sockets fitted therein.

1 would state in conclusion that while the illustrated and describedexamples constitute one practical embodiment of my invention, I do notlimit myself strictly to the exact details herein illustrated since,manitestly, the same can be considerably varied without departure fromthe spirit of the invention as defined in the appended claim.

lVhat I claim as my invention is An ii'iscrtahle pipe joint of the belland spigot type comprising a tubular body, one end of which is enlargedto form a socket or bell designed to receive the spigot end 01? 'asucceeding length of pipe, said bell and tubular body being providcd'with a reinovahle wall section, the plane (it division therc etweenextending axi'ally through the hell i d thence outwardly through theside wall at the tubular body on a transverse pl'ane inclined downwardlyfrom said bell, and intersecting the akial plane at substantially thepoint where the bell and tubular body portioii merge, said bedy. belland removable wall section adjacent the meeting edges ther'eot beingprovided with outwardly extending flanges. fastening devices cooperating with the flanges for securing the flanges together and areinforcing enlargement integral with the tubular body and with thetubular body and with the portion of the flange thereof that underliesthe central portion of the removable wall section, one of the "fasteningdevices also cozi'cting with the reinforcing enlargement.

I In reami a whereof; I hays signed my name to this specification this8th day of November; 19:24. i
